Currently, Opera Sync only allows users to view a static list of open tabs from other devices.
I propose a True Real-Time Tab Mirroring feature:

1. Unified Tab State: Tabs should be identical and active across all signed-in devices (Desktop, Mobile, Tablet) in real-time.
2. Cross-Device Closing: When I close a tab on my smartphone, it should automatically and instantly close on my desktop browser (and vice versa).

Why this matters to me:
To be completely honest, the lack of this feature is currently a dealbreaker for me. Managing identical tabs manually across multiple devices is too time-consuming. Without a true, seamless real-time sync, I will unfortunately have to uninstall Opera and switch back to a competitor that supports this workflow. I love the browser otherwise, but this is a critical productivity feature for my daily use.

Thank you for considering this feedback!
